I'm still trying to keep my son believing in Santa Claus. He is seven now and has heard some of the older kids talking in school about Santa not being real. I think that is the most common way for kids to find out these days. My wife and I decided to try ordering a letter from Santa for him this year. We looked at several different websites and settled on www.ezsantaletters.com. They have a wider variety of letters that can be personalized and offer some other interesting products, like a Santa Evidence Kit. I am thinking about getting that one too.
